Chrome: If you frequently search for image files when you encounter new animals, foods, and other words you can save time by installing Image Dictionary, a Chrome extension that can automatically display Wikipedia images for a word using a mouse clicks.

You can utilize the extension by highlighting and right-clicking a word or by holding down the ALT key and double-clicking a word. The first image result for the Wikipedia entry for that word will appear in your browser window and you then click on the image to close. The photo also offers a direct link to the Wikipedia page for the entry and the image page.

This is a somewhat handy app but many Wikipedia entries use multiple images and it would be nice to have a way to cycle through those. It's not for everyone but if you by nature curious this extension might be for you.
